Just went out to look at the car and the button has popped back out.  It
will stay on low vent unless I leave the system off for a while, then
when I turn it back on, it needs to be re-selected for where to blow the

Hi Scott,

Yes, this is a very common problem.  It mainly stems from the cup holder
that is mounted on the dash, and typically spills coke and other
sugar-laden drinks down upon the radio and climate control buttons.  I
have seen a detailed article on removing all of those buttons and
cleaning them out... I think it was on s-cars.org?  But as a quick
temporary fix, you could spray some wd-40 along the edges of the buttons
that are stuck and work them loose, then use some compressed air to blow
out any gunk that is still in there.
